720 CE
Leo seals an alliance with his associate Artabasdos by marrying his daughter Anna to him.
(Throughout Leo's reign, Artabasdos will remain the second most powerful man in the empire by virtue of his control of several important military posts.)
Leo's wife, Maria, had in 718 borne him a son, Constantine, whom he crowns in 720.
